Treatment of Synthetic Urinous Wastewater Using Combined Reverse Osmosis, Immobilized Urease, and Ion Exchange Systems
Abstract
A collagen-urease membrane complex of relatively stable enzymatic activity was successfully produced. In order to evaluate the potential use of this complex for the treatment of urinous wastewater, a biocatalytic reactor module of a novel spiral wound configuration was constructed and integrated into a prototype system containing reverse osmosis and ion exchange processes. The unit that was designed and constructed was sized so as to be capable of generating sufficient process data that could be used in the estimation of the system design parameters. This work was accomplished by using a synthetic urinous feed solution containing sodium chloride and urea as the major contaminants. The performance of the biocatalytic reactor module was simulated using a transport model consisting of factors which account for simultaneous mass transfer and biochemical reaction. The model was based upon the assumptions of steady-state, plug-flow, and Michaelis-Menten kinetics. From this model, the apparent Michaelis-Menten kinetic parameters were estimated and computer simulated curves were compared to the actual performance data of the biocatalytic reactor module under a variety of reactor feed flow rates and urea concentrations.
